Racing Hall of Fame inductee, Miesque who twice won the Breeders' Cup Mile.
Trained by François Boutin, in 1994 East of the Moon won three Group One races: the Prix Jacques Le Marois, Poule d'Essai des Pouliches and the most prestigious race for Three-Year-Old fillies, the Classic Prix de Diane.
Retired to Stavros Niarchos's Oak Tree Farm near Lexington, Kentucky, East of the Moon had the first of her nine foals in 1996, none of which were able to match her success on the track – however, her daughter Alpha Lupi is the dam of three Group One winners in Alpha Centauri, Alpine Star and Discoveries.
East of the Moon died at Oak Tree Farm in 2006 after being struck by lightning.
